Process Flow of HF Pipe Mill
The characteristics of theHF pipe mill are: high speed, small welding heat affected zone, no need to clean the workpiece during welding, and the ability to weld thin-walled pipes and metal pipes.
The production process of HF Tube mill mainly depends on the product material. A series of processes are required from raw materials to finished products. In order to complete these processes, it requires corresponding various mechanical equipment, such as welding, electrical control, and testing devices. These equipment and devices are based on different requirements. The process flow requires a variety of reasonable arrangements. The typical process of high-frequency tube mill is: slitting - uncoiling - strip leveling - head and tail shearing - strip butt welding - loop storage - forming - welding - deburring - sizing - Flaw detection - flying cutting - initial inspection - steel pipe straightening - pipe section processing - hydraulic test - flaw detection - printing and coating - finished product.
